Abstract: The selectable one-way clutch includes a pocket plate, a notch plate, a cover plate, and plate-like struts. A one end portion of each strut is provided with an engagement surface and a projecting portion. Each strut comes into an erect state in which the engagement surface of the strut erects from the other surface of the cover plate toward the notch plate side. The selectable one-way clutch moves the notch plate in the axial direction to change a distance in the axial direction between the pocket plate and the notch plate, thereby carrying out switching between an out-of-engagement state in which the erecting struts cannot contact with the notches and a one-way clutch state in which the erecting struts can contact with the notches.

A leading end of the plunger from the joint is also supported while being allowed to reciprocate by a supporting member formed integrally with a stationary member to which the casing is fixed.

In order to reduce a drag torque resulting from a cranking of an engine to bring the selectable one-way clutch into engagement mode, the control system raises a temperature of lubrication oil before carrying out the cranking of the engine if it is too low, and carries out the cranking of an engine by a motor after the temperature of the lubrication oil is raised to a level at which viscosity thereof is reduced.

Abstract: A selectable one-way clutch includes a fixed plate, a rotatable plate, a switching plate, an arm member, and an actuator including an operating shaft member for moving the arm member. Lubricating oil is interposed between any adjacent two of the fixed plate, the switching plate and the rotatable plate. Where a first distance is a distance from a rotation center of the switching plate to a contact point of an operating portion of the arm member and a first contact portion of the operating shaft member in normal switching operation from a disengaged state to an engaged state and a second distance is a distance from the rotation center of the switching plate to a contact point of the operating portion of the arm member and a second contact portion of the operating shaft member in switching plate erroneous operation, the second distance is larger than the first distance.

Abstract: A selectable one-way clutch includes an engagement mechanism. The engagement mechanism is configured to be switched between an engaged state and a disengaged state. The engaged state is a state in which relative rotation between a first and a second members in one of a positive rotational direction and a reverse rotational direction is restricted. The disengaged state is a state in which the relative rotation between the first member and the second member in both of the positive and the reverse rotational direction is permitted. The electronic control unit is configured to apply torque to the one of the first member or the second member by using a motor such that relative rotation in the other one of the positive or the reverse rotational direction is generated between the first member and the second member when the engagement mechanism is switched from the engaged state to the disengaged state.
